Versuchsvorschrift

2-(4-Chloro-3-methoxy-2-pyridinyl)-acetonitrile (7.06 g) is dissolved in THF (40 ml) and 60% sodium hydride (1.62 g) is added followed by 3.25 ml of ethyl iodide. The reaction is allowed to stir at 45° C. for 1.5 hour then the reaction mixture is diluted with water and extracted with ethyl acetate. The desired product is purified by chromatography using hexane/ethyl acetate 4/1 as solvent.
